Jonathan Ellis commented on CASSANDRA-2061:
-------------------------------------------

STPE also notes,

bq. While this class inherits from ThreadPoolExecutor, a few of the inherited 
tuning methods are not useful for it. In particular, because it acts as a 
fixed-sized pool using corePoolSize threads and an unbounded queue, adjustments 
to maximumPoolSize have no useful effect.

We've wanted bounded queues in the past, and we definitely still use growable 
pools in places, so that's another reason to keep both.
